目的探索老年大肠癌的临床病理特点。方法对１１７例老年人大肠癌的病理资料进行回顾性分析，并与对照组进行比较。结果老年组大肠癌占老年大肠肿瘤的５５．４５％，高于对照组（Ｐ＜０．０５），其中绒毛状腺癌明显高于对照组（Ｐ＜０．０１），而粘液腺癌和粘液细胞癌则明显低于对照组（Ｐ均＜０．０５）。老年大肠癌的浸润深度明显浅于对照组（Ｐ＜０．０５），而其转移率则与对照组无明显差别。老年大肠癌的好发部位与其他年龄有所不同，依次为直肠、乙状结肠、回盲部、降结肠、肝曲、升结肠、横结肠和脾曲。结论老年大肠癌发病率高于其他年龄，老年大肠癌的组织类型与其他年龄有所不同，且老年大肠癌的局部侵袭力低于其他年龄。老年大肠癌发生部位与其他年龄有所不同
Objective To explore the clinicopathological features of colorectal cancer in elderly patients. Methods The pathological data of 117 elderly patients with colorectal cancer were retrospectively analyzed and compared with the control group. Results The colorectal cancer in the elderly group accounted for 55.45% of the elderly colorectal tumors, which was higher than the control group (P<0.05). The villous adenocarcinoma was significantly higher than the control group (P<0.01), while the mucinous adenocarcinoma and Mucinous cell carcinoma was significantly lower than that of the control group (P all < 0.05). The depth of invasion of elderly colorectal cancer was significantly shallower than that of the control group (P<0.05), while the metastasis rate was not significantly different from that of the control group. The predilection sites of older colorectal cancers are different from those of other ages, including rectal, sigmoid, ileocecal, descending colon, hepatic flexure, ascending colon, transverse colon, and splenic flexure. Conclusions The incidence of colorectal cancer in elderly patients is higher than that of other ages. The tissue types of elderly colorectal cancer are different from those of other ages, and the local invasiveness of elderly colorectal cancer is lower than other ages. Older colorectal cancer is different from other ages
